QUESTION: 1

Solution:
QUESTION: 2

Solution:
QUESTION: 3

### Young's modulus is defined as the ratio of

Solution:

The linear relationship between stress and strain for a bar in simple tension or compression can be expressed by the equation in which Eis a constant of proportionality known as modulus of elasticity for the material. The modulus of elasticity is the slope of the stress- strain diagram in the linearly elastic region and its value depends upon the particular material being used.

QUESTION: 4

Match List-I (Material) with List-ll (Young’s modulus):   Solution: QUESTION: 5

The permanent mode of deformation of a material known as ____________

Solution:

Plasticity is defined as the property of a material due to which it is permanently deformed due to loading. Elasticity is the temporary form of deformation. Twinning and Slip are mechanisms of Plastic deformation.

QUESTION: 8

During a tensile test on a specimen of 1 cm2 cross-section, maximum load observed was 80 kN and area of cross-section at neck was 0.5 cm2. UTS of specimen is

Solution: = 800 MPa

QUESTION: 9

A prismatic bar of circular cross-section is loaded by tensile forces P= 90 kN. The bar has length L = 3 m and diameter d = 30 mm. If is made of aluminium with modulus of elasticity E = 70 GPa and Poisson’s ratio v = 1/3. What is the increase in volume ΔV of the bar?

Solution:   QUESTION: 10

Resilience of a material is considered when it is subjected to

Solution:

Resilience represent the ability of the material to absorb energy within the elastic range.
